21.O you who believe! Follow not the footsteps of Shaytan. And whosoever follows the footsteps of Shaytan, then, verily he commands Al-Fahsha’ [i.e. to commit indecency], and Al-Munkar [i.e. to do evil and wicked deeds]. And had it not been for the Grace of Allah and His Mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to Islam) whom He wills, and Allah is All-Hearer, All-Knower.
